CVE-2026-33310

EIP tracks 1 public exploit for CVE-2026-33310. PoCs published by redyank.

AI-analyzed exploit summary The repository contains a functional PoC for CVE-2026-33310, demonstrating command injection via shell() expansion in parameter defaults within Intake catalog YAML files. The exploit leverages the automatic expansion of shell() syntax during catalog parsing to execute arbitrary commands.

Intake is a package for finding, investigating, loading and disseminating data. Prior to version 2.0.9, the shell() syntax within parameter default values appears to be automatically expanded during the catalog parsing process. If a catalog contains a parameter default such as shell(<command>), the command may be executed when the catalog source is accessed. This means that if a user loads a malicious catalog YAML, embedded commands could execute on the host system. Version 2.0.9 mitigates the issue by making getshell False by default everywhere.
